Hi!
We use a CISCO 5350 for dial-in and dial-out functons.
The ppp ISDN and ppp analog dial-in work with single-line or ppp multink.
The ISDN PPP callback works on single-line.
When i try the multilink capability the NAS callback single-line only.
The debug isdn q931 shows one isdn call only.
Why does not NAS try the open the secondary ISDN channel??
Here is the config.
Thanks

It's difficult to say without debug; in particular, "debug ppp neg", "debug callback", "debug isdn q931", "debug aaa authen", and "debug aaa author". This debug should indicate what the problem is in calling back a second time.

Hi!
Here is the debug output what you asked. i set the 'debug ppp multilink event' too which show the traffic is above the threshold on the interface.

You have a load-threshold configured on the serial interface, but no dialer map. If you want to use MPPP BOD for the remotes, it would be best to have the remotes initiate a second call (configure a dialer load-threshold on them); otherwise, you will need to configure a static dialer map for each remote that should be called back a second time. And with a dialer map, you would need to configure a "class" option with it to authorize callback in the first place.

Hi!
Yes. I see this solution in many examples.
But we have got many of users. It is not possible to make many-many STATIC Dialer map.
I would like that NAS initiates the second call immediately ( or later ) by AAA information ( DIALER STRING, USERNAME )
IS IT POSSIBLE OR I'LL FORGET THIS POSSIBILITY?
ps.
Unfortunetly my ISDN ( Zyxel omni.net plus ) TA does not make a second call after callback. The client ppp Mppp works dial-in only.
11-18-2002 09:53 AM
The dialer maps are not required if you have the remotes initiate the second call; this only requires the addition of the "dialer load-threshold" command on the remotes, if using cisco's.
If you want the NAS to intitiate the second call, you need the static dialer maps. You could have a look at Large Scale Dialout (this would elimiate the need for a map), although I'm not sure that this would work given that the first connection would not be brought up using LSDO.
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fdial_c/fnsprt11/dafsdil.htm
Having the remote's initiate both the first and second call would likely be the easiest to maintain. I'm not familiar with the oomni.net, but if it supports MPPP and dialout it should support the dialing of a second link.
